DISK GAS HOLDER.

Application filed May 13, 1925, Serial No, 29,894, and in Germany November 1, 1924.

In existing constructions of disk gas holders with a sealing disk and a liquid seal between the wall of the gas holder and the rim of the sealing disk, the sealing liquid is continuously maintained in circulation, by having the liquid, which trickles through the gap, collect at the bottom of the gas holder, and conveyed back to the upper end of the gas holder, so that it. will again trickle down the wall of the gas holder, to the sealing disk. Many gas works receive electric current, which is used for driving the pumps, whereby the sealing-liquid is circulated from distant power stations, which as known are subject to occasional interruptions of service, lasting for several hours or also for a longer time andconsequently cause a corresponding interruption in the operation of said pump. Since these interruptions of service in most cases take place after a lightning storm or the like, that is during the hottest season, at which time the quantity of the sealing liquid passing through the ,gap is largest, it is desirable to provide a certain reserve of liquid at the top of the gas holder, said liquid being employed in case the normal circulation thereof is interfered with.

This invention relates to a device serving to provide such a reserve of sealing liquid. This device on account of its great simplicity may be added as an auxiliary to the normal service without causing any difficulties in the operation of the plant.

This invention consists essentially therein, that the sealing liquid at the top of the gas holder is not immediately passed to the distributing box, from which it trickles down over the inner surface of the gasholder, but that it is first conveyed to a storage container, from which it will be caused to flow to the distributing box by means of an overflow tube. In this manner, therefore,'the storage container will normally always contain a supply of sealing liquid and only the surplus of this liquid is conveyed to said distributing box. At the bottom of the aforementioned storage container, however, there is further provided a valve or a similar appliance through which the contents of the storage container may be discharged into the distributing box in case of need, that is to say, at times, when the circulation of the liquid is temporarily interfered with.

This valve or similar appliance will be opened after such a quantity of liquid has discharged at the sealing disk that there will be danger of gas passing through theggap by reason of its internal pressure overcom mg the resistance of the sealing liquid. The reserve capacity of the storage container, is preferably such that the amount of sealing liquid held in reserve is capable of being properly accommodated by the sealing device with which the sealing disks ofgas holders of the indicated type are generally provided. In other words the reserve capacity of the storage container is based. upon the amount of sealing liquid which is capable of being taken up by the aforesaid sealing device without disturbance of the intended sealing operation and without overflow loss of sealing liquid; if more than one storage ment the previously mentioned valve may,

simply be opened when necessary and left in this condition without further attention, as in no event will it be possible to discharge more sealing liquid than can be properly ac-,

commodated by the sealing device of the seal ing disk. This arrangement is important, because this valve is'positioned at the top of the gas holder, that'is at the height of a tower above the ground, and is therefore diflicult to reach and still more diflicult to control. If the liquid is again started in circulation by the pumps it will initially be of no disadvantage, if the valve remains open, and it will be sufficient, if the valve is closed as soon as convenient, thus again filling the storage container with sealing liquid to serve as a reserve. Under normal conditions care should be taken, that the valve is closed, as soon as the pumps are put again to work, so that a reserve is present as early as possible. In any case, it may be added, mistakes which may be made by an operator in handling the device will have no detrimental effect.

In the drawing an example of the device for supplying the sealing liquid according to this invention is shown, Fig. 1 being a fragmentary elevation of a gas holder with the device mounted on the wall thereof and Fig. 2 a diagrammatic vertical section through Fig. 1.

On the wall a of the gas holder, the distributing box I) is arranged, from which the sealing liquid may trickle down through an overflow opening 6 in the wall extending William the gasometer.

over some length and having a serrated conformation as shown in Fig. 1. Immediately above this distributing box I) there is provided a sealing liquid storage container 0, which is equipped at its interior with an overflow tube d. This overflow tube is so arranged, that the storage container is always kept filled with liquid and that only the surplus of liquid will pass into the distributing box I) from which the liquid will flow through the overflow opening 7) into the body of sealink liquid 9 surrounding the closure disk h of The liquid is supplied to the storage container 0 by means of a suitable pipe 6. Preferably a plurality of devices of the aforedescribed construction each comprising a storage container 0 and a distributing box as shown, is provided on the wall a at various circumferentially spaced points of the gas holder.

At the bottom of each of the storage containers 0 there is provided a valve or faucet f,wh1ch is normally closed and which Wlll be opened as soon as the supply of sealing liquid is interrupted for a considerable time. The contents of liquid in the storage con v tainer 0 will serve in this case as a reserve and may for a considerable perlod safely maintain the operationof the gas holder.

I claim:

1. In a disk gas holder, the combination of a sealing liquid storage container, a distribut ing box below said container, said container and said distributing box being mounted at the upper part of the gas holder, means for supplying sealing liquid to said container, an overflow tube provided in said container for discharging a surplus of liquid contained in the latter into said distributing box, and a valve at the bottom of said container, for discharging the contents of said container into said distributing box.

2. In a disk gas holder, the combination comprising a sealing liquid storage container, a distributing box mounted at a lower level than said container on the outside of the upper part of the gas holder, said holder having an overflow opening in its wall in registry and communicating with said distributing box, means for supplying sealing liquid to said container, a conduit leading from the lower part of said container to said distributing box for conducting the contents of said container to said overflow opening, a Valve for shutting off: said conduit, and a second overflow conduitleading from said container to the interior'ot the gas holder and having its inlet located at a level near the top of said container for discharging a surplus of liquid in said container while said valve is closed.

3. In a disk gas holder, the combination comprising a sealing liquid storage container, a distributing box mounted at a lower level than said container on the outside of the upper part of the gas holder, said holder having an overflow opening in its wall in registry and communicating with said -distributing box, means for supplying sealing liquid to.
